不需要来自 example.com/{lang}/index.php 的 index.php

Question

My .htaccess currently looks like:

RewriteEngine On

RewriteCond %{THE_REQUEST} \s/+([^/]+)/\?lang=([^\s&]+) [NC]
RewriteRule ^ /%2/%1? [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([a-z]{2})/([^/]+)/?$ $2/?lang=$1 [L,QSA]

Which means that example.com/{lang}/some-page.php acts as example.com/some-page.php?lang={lang}

Remaining issue: example.com/{lang} does not work unless it has index.php like `example.com/{lang}/index.php

How can I make it work when we go directly to example.com/{lang} ?

How about this:

RewriteEngine On

RewriteCond %{ENV:REDIRECT_rewritten} !=1
RewriteCond %{QUERY_STRING} ^lang=([a-z]{2})$ [NC]
RewriteRule ^([^/]*)$ /%1/$1? [R=301,L]

RewriteCond %{REQUEST_URI} !^/js/
RewriteRule ^([a-z]{2})(?:/([^/]+))?$ $2?lang=$1 [NC,L,QSA,E=rewritten:1]

I really don't like matching on THE_REQUEST so changed that. This also redirects just /?lang=xx which you may not want. I used the same matching for lang strings in both rules which you may not want. Let me know.

Not sure you need the file or directory existence checks and it is slowing things down a bit if not necessary, as the filesystem must be polled twice on every request. Do you have two letter files or directories in root?
